The Federation of American Scientists has created two tools to estimate the destructive impact of a nuclear "bunker buster" bomb. The blast-effects calculator illustrates the immediate destruction that occurs in the moments following a detonation. Specify bomb yield and location, and the calculator produces a blast diagram superimposed over a satellite image of the selected city. Use the fallout calculator to trace the four-day radiation pattern that results from the initial blast. You can specify wind speed and direction for a given location.
